ARM: tegra: timer: Fix us timer time after resume from LP1

In LP1 suspend, or during a failed LP0 suspend, the core power is
not turned off and the timer register is not reset.  Saving the
timer value during suspend and adding it to the offset after resume
will cause the timer value to double for each suspend cycle.

To fix, when resuming subtract the current value of the timer
register from the offset.  Also, use the rtc registers to add
the time that passed during suspend.

ARM: tegra: timer: Remove 32k clocksource

The 32k clocksource is never used, because it is always registered
at the same time as the us clocksource, which has a higher rating.
Using the 32k clocksource would cause a race condition with the
tegra_rtc driver on the RTC shadow registers.  Remove the 32k
clocksource, add a replacement tegra_read_rtc_ms function for the
suspend code to track suspend time, and add a comment on
read_persistent_clock that it should never be called while the
tegra_rtc driver is running.  It is currently only called from
timekeeping init, suspend, and resume.
